| Abstract: | A method of biologically decolorizing wastewater from fiber reactive dyeing of cotton by sequential anoxic/aerobic treatment steps using a single biomass has been developed and evaluated for chemical oxygen demand and color removal. A viable biomass that effectively removes both color and chemical oxygen demand in a sequential anoxic/aerobic treatment process has been developed. This method may be retrofitted to existing aerobic wastewater treatment systems that are typically used to treat dyeing wastewater. Copyright © 2006 Society of Chemical Industry |
